Lamp structure

Abstract

A lamp structure includes a case, a fixing base and a plurality of heat dissipation members. The fixing base is disposed at the case and comprises a carrier. The heat dissipation members are coupled to the fixing base, wherein a heat exchange space is defined between adjacent heat dissipation members. The heat produced from the lamp structure can be dissipated through the heat dissipation members and the heat exchange space so as to increase heat dissipation efficiency of the lamp structure. Therefore, the present invention prevents the lamp structure from overheat to avoid a relatively lower optoelectronic conversion efficiency or destruction.
